Sea-ice core and under-ice optical measurements from ice stations conducted during RV Polarstern PS117 voyage

Sampling and analyses followed standard procedures (e.g. Miller et al. 2015). No problems were encountered. Sea-ice cores (0.09 m internal diameter) were sampled during Polarstern voyage PS117 to the Weddell Sea during December 2018 to January 2019. Ice core measurements include position, snow thick...

Description
Summary:Sampling and analyses followed standard procedures (e.g. Miller et al. 2015). No problems were encountered. Sea-ice cores (0.09 m internal diameter) were sampled during Polarstern voyage PS117 to the Weddell Sea during December 2018 to January 2019. Ice core measurements include position, snow thickness, ice thickness, ice core temperature and bulk-salinity profiles, macro-nutrient concentrations as well as Chlorophyll-a pigment content. In addition on each ice station downwelling (surface) and under-ice irradiances were measured with a hyperspectral radiometer. Combined these measurements aimed i) to describe physical-chemical-biological conditions in summer sea ice in the Weddell Sea and ii) to develop algorithms to estimate sea-ice Chlorophyll-a content from transmitted irradiance data (see for example Melbourne-Thomas et al. 2015, Meiners et al. 2017).
